Cradle assembly
Abstract
Abstract A ROCKING CRADLE ASSEMBLY INCLUDING A MAIN UPRIGHT FRAME SUSPENDING A CRADLE FOR LATERAL MOVEMENT IN A PLANE PARALLEL TO A SUPPORT SURFACE. AN ELECTRIC MOTOR IMPARTS RECIPROCATING MOTION TO THE CRACDLE THROUGH AN ECCENTRIC CAM AND LINKAGE. THE LINKAGE IS DISPOSED BETWEEN THE CAM AND CRADLE, AND CONSISTS OF A PAIR OF OVERLAPPED, PIVOTALLY CONNECTED LINKS NORMALLY PREVENTED FROM MOVING RELATIVE TO EACH OTHER BY A TENSIONED COIL SPRING HAVING AN END CONNECTED TO EACH LINK. THE MOTOR ROTATES THE CAM WHICH OSCILLATES THE LINKS IN UNISION, WHICH, IN TURN, IMPARTS MOTION TO THE CRADLE. IF THE CRADLE IS MANUALLY IMMOBILIZED, ONE LINK OSCILLATES AND PIVOTS RELATIVE TO THE OTHER, ENABLING THE MOTOR TO CONTINUE TO OPERATED AND THE CRADLE TO DWELL, WITHOUT ANY DETRIMENTAL EFFECTS TO THE DRIVE SYSTEM. THIS MOTION OCCURS TO A LESSER EXTEND AT THE END OF EACH RECIPROCAL STROKE OF THE CRADLE, THEREBY CUSHIONING THE RECIPROCAL MOTION OF THE CRADLE AT THE END OF EACH STROKE AND PROVIDING A SMOOTH, GENTLE ROCKING EFFECT.
